On This Day in Music History:

June 25th: On this day

1964, Roy Orbison was at No.1 on the UK singles chart with 'It's

Over', his second UK No.1. Orbison was the first American artist

to score a UK No.1 in the past 47 weeks.

1966, The Beatles started a two week run at No.1 on the US

singles chart with 'Paperback Writer', the group's 12th US No.1.

The track is marked by the boosted bass guitar sound

throughout, partly in response to John Lennon demanding to

know why the bass on a certain Wilson Pickett record far

exceeded the bass on any Beatles records. It was also cut louder

than any other Beatles record, due to a new piece of equipment

used in the mastering process.
